UK Employees Working Abroad: Legal And HR Considerations For Employers

If you run a small business, you’ve probably had the “Can I work from abroad for a bit?” conversation at least once.

Maybe a key team member wants to spend a month in Spain, a developer asks to relocate to Portugal, or a sales lead needs to work from the US while caring for family. In a world of remote work, these requests are normal - but the legal and HR risks can sneak up on you if you treat it like a simple change of scenery.

This guide is written for employers, and it’s designed to help you manage overseas remote working in a way that protects your business, your people, and your ability to keep operating smoothly. We’ll focus on the key issues you should think through when an employee is working abroad for a UK company, whether that’s for a short period or a longer-term arrangement.

Why Employees Working Abroad Changes The Compliance Picture

When an employee is based in the UK, you generally know the “rulebook” you’re operating under (even if it still feels a bit complicated).

When an employee is working overseas, you may suddenly be dealing with:

• Two legal systems at once (UK employment law plus mandatory rules in the host country);
• Tax and payroll complexity, including overseas income tax obligations and social security questions;
• Immigration and right-to-work risk (some “remote working” is still “working” for visa purposes);
• Permanent establishment exposure (in some scenarios, overseas activity can create corporate tax risks);
• Data protection and cybersecurity issues, especially if data is accessed from outside the UK;
• Health and safety duties in a very different environment (even if they’re “just working from a laptop”).

None of this means you can’t say yes. It just means you’ll want a clear process - and a written agreement - before you approve the arrangement.

As a general rule, the longer the overseas stay and the more “embedded” the employee becomes in the host country, the more legal obligations you may trigger. Country-specific rules vary, so you’ll often need local advice for the destination in question.

Set The Scope: Temporary, Hybrid Or Relocation

Before you get into the technical legal questions, get practical clarity on what’s actually being requested. This is one of the fastest ways to reduce risk and avoid misunderstandings later.

1) How Long Will They Be Abroad?

It’s common to hear “just a few weeks” - and then a few weeks turns into three months, then six. A good approach is to approve a defined period, with any extension requiring a new review.

If you’re dealing with a UK employee working abroad temporarily (for example, 2–8 weeks), your compliance work is usually lighter than a full relocation. But you should still do checks around immigration, insurance, and data security.

2) Where Will They Work From?

“Abroad” isn’t one jurisdiction. Different countries have different:

• employment protections that apply regardless of contract wording;
• tax residency rules;
• data transfer rules and sector requirements;
• public holiday rules and working time limits.

Ask for the exact country (and, ideally, city) and whether they’ll be moving between locations.

3) Are They Still Doing The Same Role?

This matters more than many employers expect. For example:

• A senior salesperson negotiating and signing deals abroad can create different tax and legal exposures than an admin worker answering emails.
• If the employee manages staff in the host country, local HR obligations can become relevant quickly.
• If their role involves handling sensitive personal data, security controls need to be tightened.

4) Will They Be An Employee Or A Contractor Abroad?

Some businesses consider switching the person to “contractor” status when they move overseas. Be careful here: relabelling someone doesn’t automatically change their legal status, and misclassification can create serious risk (including claims for employment rights and tax issues).

Usually, if you want the arrangement to stay stable and low-risk, you keep them as an employee and document the overseas working arrangement properly within the existing employment relationship.

This is also a good point to check whether your existing Employment Contract allows you to approve overseas working, and whether it has the flexibility you need around place of work, mobility, and policies.

Get Clear On Employment Law And Working Time

A common misconception is: “They’re employed by a UK company, so UK employment law applies and that’s the end of it.”

In reality, when employees work abroad, local mandatory employment rights in the host country can apply, even if the contract is governed by English law. Exactly when (and which rights) will depend on the country and the specific working arrangement, so treat this as a prompt to check the host country position rather than a one-size-fits-all rule.

What you’re trying to do as an employer is:

• keep your existing UK employment framework in place (as far as you can), while
• identifying and complying with any non-negotiable local requirements that could override your contract terms.

Minimum Standards And “Mandatory” Local Rights

Depending on the country, mandatory rights can cover things like:

• minimum paid holiday and holiday pay calculation methods;
• limits on probation periods;
• requirements for written employment terms in a particular format or language;
• termination protections (including extra notice, consultation duties, or severance);
• rules around sickness absence and medical evidence;
• rights to disconnect, working time recording, or overtime restrictions.

Even if you don’t end up with a dispute, failing to meet mandatory local standards can cause issues if your employee later raises a grievance, refuses to follow directions, or challenges a dismissal.

Working Time, Rest Breaks, And Expectations

When employees are working across time zones, it’s easy for boundaries to blur - especially in startups where everyone’s trying to move fast.

From a UK perspective, you should still keep an eye on compliance with the Working Time Regulations (and the employee’s wellbeing), especially where the “always online” culture creates unpaid overtime or burnout risk. If you need a quick refresher on the rules, Working Time Regulations is a useful starting point.

From an HR perspective, it’s smart to set clear expectations on:

• core working hours (especially for collaboration);
• how breaks will be taken;
• how overtime is requested and approved;
• how you’ll measure performance (output-based metrics are often better than “online presence”).

Health And Safety Doesn’t Disappear

Even if your employee is working from an apartment overseas, you still have health and safety duties as their employer.

What’s “reasonable” will depend on the role and location, but typically this means:

• making sure they have a safe workstation setup (DSE-style considerations);
• having a process to report incidents or hazards;
• considering travel safety if the working arrangement involves frequent movement;
• checking your insurance coverage (employers’ liability, travel, equipment).

Having a clear Workplace Policy suite (including remote working and health & safety expectations) can make this much easier to manage consistently across the team.

Handle Tax, Payroll, Immigration And Social Security

This is often where employers get caught out - not because they’re trying to do the wrong thing, but because the risks aren’t obvious until someone asks a very specific question.

When an employee is based overseas, you may need to deal with tax and immigration issues in both the UK and the host country. This section is general information only: tax, National Insurance/social security and immigration rules are highly fact-specific, and you should get advice from a qualified tax adviser and/or immigration specialist (and, where appropriate, local advisers in the destination country) before approving anything beyond a short trip.

Payroll Withholding And Income Tax

If an employee works in another country, the host country may treat their salary as taxable there, and require:

• local payroll withholding, and/or
• employer registration, and/or
• reporting obligations.

The UK may still also have tax withholding expectations depending on the employee’s UK tax residency position and how your payroll is structured.

Double tax treaties can help prevent being taxed twice, but they don’t remove admin obligations automatically. This is where you’ll usually want early input from a tax adviser - especially if the arrangement might extend or become ongoing.

Social Security (NI) And Local Contributions

For social security, you may need to work out whether:

• UK National Insurance continues to apply;
• the employee needs to contribute to the host country’s social system; and
• you, as the employer, have employer-side contribution obligations abroad.

The answer often depends on where the employee is going and how long they’ll be there.

Immigration And Right To Work

Even if someone is “just working remotely”, many countries treat this as work for immigration purposes.

As an employer, you should avoid informal assumptions like “they’re on a tourist visa so it’s fine.” If the person doesn’t have the correct permission to work, you can end up with:

• the employee being refused entry, fined, or removed;
• reputational damage for your business;
• disruption to projects and client commitments.

A sensible baseline is to treat visa and right-to-work compliance as something you actively verify for the arrangement (typically with specialist immigration input for the destination), rather than relying on the employee to self-certify.

Permanent Establishment (Corporate Tax) Risk

This one is easy to miss, but it can be significant.

If an employee is working overseas and:

• regularly negotiates or concludes contracts,
• acts as a local representative of your business, or
• creates a fixed place of business (depending on the facts),

your company may risk creating a “permanent establishment” in that country, which can lead to corporate tax exposure and reporting obligations there.

This risk is very fact-specific - but it’s one of the reasons it’s worth having a formal approval process rather than an ad hoc “sure, go for it”.

Protect Data, IP And Security When Staff Work Overseas

When people picture “employees working abroad”, they usually think of laptops by the pool and flexible hours.

From a business risk perspective, the bigger issue is often data and confidentiality - because an overseas location can change your threat profile overnight.

UK GDPR Still Applies (And Cross-Border Access Matters)

If you handle personal data (customer data, employee HR files, contact lists, client records), you need to keep complying with the UK GDPR and the Data Protection Act 2018.

When an employee accesses personal data from outside the UK, you should treat it as a trigger to review your security measures and, where relevant, whether your arrangement involves restricted international transfers or other cross-border compliance steps. This can be a nuanced, fact-specific area (and it can differ depending on where people, systems, and suppliers are located), so get advice if the facts are complex.

For many small businesses, a practical first step is making sure you have your GDPR compliance foundations in place - for example a GDPR package that matches how you actually collect, store, and use data.

Set Clear Acceptable Use And Device Rules

Overseas working often means:

• more public Wi-Fi (cafes, coworking spaces, airports);
• more device travel (greater theft/loss risk);
• more informal working setups (shared accommodation, family around, screen privacy issues).

It’s worth setting expectations in a written Acceptable Use Policy so your team knows what’s allowed and what’s not (for example, VPN requirements, password standards, restrictions on personal devices, and rules on downloading data locally).

Confidentiality, Client Requirements, And NDAs

If you work with corporate clients, you may already be subject to contractual security requirements. Sometimes clients prohibit certain data from being accessed outside the UK (or outside approved territories).

So before you approve an employee working abroad, check:

• your client contracts and security addenda;
• any sector-specific requirements (for example, regulated industries);
• where your systems and servers are hosted, and who can access what.

If you use overseas suppliers (like cloud tools, HR systems, or IT support) to support remote work, it’s also worth checking whether you need a Data Processing Agreement in place with the relevant provider.

Protecting Intellectual Property (IP)

Most small businesses rely heavily on their IP - code, content, designs, processes, product ideas, marketing materials.

When an employee is working overseas, you’ll typically want to ensure:

• your employment documentation clearly confirms IP created “in the course of employment” belongs to the business;
• confidential information is protected and can’t be reused later;
• the employee understands what can and can’t be stored locally or shared with third parties.

This tends to come back to having properly drafted employment terms, plus clear internal policies that your team actually follows in practice.

Put It In Writing: A Practical Checklist For Approving Overseas Work

Once you’ve decided you’re open to the request, you’ll want to document it so everyone is clear on the rules. This isn’t about being rigid - it’s about protecting the relationship and avoiding messy disputes later.

What To Document (At A Minimum)

For most small businesses, a “working abroad” letter or addendum should cover:

• Location (country/city) and confirmation the employee must tell you if this changes;
• Duration (start/end date) and whether an extension is possible;
• Working hours and availability expectations (including time zone alignment);
• Role and reporting (what stays the same, what changes);
• Salary and benefits (and who pays for additional costs, if any);
• Tax and immigration responsibilities (often including an obligation on the employee to comply with local laws and provide information you reasonably request, alongside any specialist advice you obtain);
• Expenses (travel, coworking, equipment, insurance, roaming costs);
• Equipment and IT security requirements (VPN, device encryption, secure storage, incident reporting);
• Data protection and confidentiality expectations;
• Right to end the arrangement (for example, you can require return to the UK on reasonable notice if business needs change).

It’s also a good moment to make sure your baseline employment documents are solid - including an up-to-date Employment Contract and practical internal policies that reflect how your business actually operates.

Build A Simple “Yes/No” Approval Process

Even if you’re a small team, you’ll thank yourself later for having a consistent process. For example:

1. Employee submits a request (dates, location, reason, role impact).
2. You do an initial risk check (duration, country, client obligations, role seniority).
3. You obtain tax/immigration input if needed (especially for longer stays).
4. You confirm security controls (device, VPN, access restrictions, training).
5. You document the arrangement (letter/addendum) and store it on file.
6. You review before extension (don’t let “temporary” become indefinite by accident).

A Quick Note On Fairness And Consistency

From an HR perspective, be careful about inconsistency. If you approve overseas working for one employee but refuse another, make sure you can explain the difference based on genuine business reasons (role requirements, client constraints, performance, security, time zone overlap), not informal preferences.

This is where clear policies and documented decision-making really help, especially as your team grows.

Key Takeaways

• When an employee works abroad for a UK company, you may trigger obligations in both the UK and the host country - especially if the arrangement is longer-term.
• Start by defining the scope: where they’ll be, how long they’ll stay, and whether their role changes while overseas.
• Mandatory local employment protections can apply even if your contract is governed by English law, so it’s worth checking the host country’s minimum standards.
• Tax, payroll, immigration, and social security issues can be the biggest “hidden” risk area - get specialist advice early for anything beyond a short trip.
• Overseas access to systems can increase data and cybersecurity risk, so make sure your GDPR foundations and internal security policies are up to date.
• Put the arrangement in writing with a clear right to review or end the overseas working setup if business needs change.
